The Democratic mayor appeared on CNN on Sunday morning. He said that he believes recall elections should be rare, but that Wisconsin is facing a rare instance.

He said Walker didn't campaign at all about his intentions to attack workers. Barrett said the governor had already extracted concessions from public workers, but then he went further and tried to permanently disarm them.

Crowley said she invited Walker to appear on her show but was told his schedule was too tight.
